PAWL=AND =RATCHET DEVICE FOR CHAIN-PUMPS.

SPECIFICATION forming part of Letters Patent No. 392,266, dated November6, 1888.

Application filed Julylfi, 1888. Serial No.280,113. (NomodclJ To allwhom it may concern.-

Be it known that I, FRED E. GORDON, a citizen of the United States, anda resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented certain new and useful Improvements in Pawl-and-Ratchet Devicesfor Chain-Pumps, of which the following is a specification, theprinciple of the invention being herein explained, and the best mode inwhich I have contemplated applying that principle so as to distinguishit from other inventions.

My invention consists in the improvements hereinafter described andclaimed.

Referring to the drawings, Figure 1 is a plan view of the well-curb andconnecting parts. Fig. 2 -is a plan view of the pawl, ratchet, andshaft. Fig. 3 is a view, partly in sectionv and partly in elevation, ofthe parts shown in Fig. 2, and taken on the dotted line of that figure.Fig. 4 is a side elevation view of the well-curb and rotary apparatuswith the cap in position. Fig. 5 is a perspective View of the cap.

A is a shaft provided with journals a a. Said journal a has bearing inthe bearingblook b, said journal a having bearing in the bearing-blockZ). This latter bearing-block is provided with the outwardly-projectinghorizontal portion 0, said portion 0 being provided with thebearing-lugs c, in which the journals (1 of the pawl d have bearings.Said pawl is composed of four portions, the upper engaging angularextremity, e, the journals (2, the lower weight portion, 0, and theshank portion a intermediate of the weight and engaging portions andangular to the latter. The angular formation of the shank and weightportion of the pawl relative to the engaging portion causes the latterto be held in close engagement with the teeth of the ratchetwheel.

Cap F is composed of the journal-cap portion f,that fits over theshaft-journal,and outer portion, f, that'incloses the ratchet wheel andpawl, said outer portion provided with the circular depressions in whichthe upper portions of the journals d respectively fit. Lugs 9, formed oneither side of the journal-cap f, respectively fit in correspondingopenings 9, formed on either side of the bearing-block b, and serve toprevent cap F from moving or slipping when placed in position. On theouter side of the ratchet is the unbroken disk h, integral with shaftand ratchet, that serves to keep the pawl from slipping sidewise off theratchet, and also serves, by engagement with the inner side of theratchet-cover, to prevent the shaft from moving endwise.

The cap is of great utilityin protecting the journal, ratchet, and pawlfrom exposure to the elements and without the necessity of extending theupper portion of the well-curb over the entire shaft and connections.The double j ournaling of the pawl is also a point of great utility, asit renders it particularly secure and easy of motion and, together withthe weight, insures the certain action of the pawl.

The foregoing description and accompanying drawings set forth in detailmechanism in embodiment of my invention. Change may therefore be madetherein, provided the principles of construction respectively recited inthe following claims are employed.

I therefore particularly point out and distinctly claim as myinvention 1. The combination of shaft A, provided with a ratchetintegral therewith, bearingblock 12, provided with theoutwardly-projecting horizontal portion 0, said portion provided withthe bearing-lugs c, and pawl d, provided with the angular portion e,engaging with said ratchet, journals d, bearing in lugs 0', and lowerweight portion, 0, substantially as set forth.

2. The combination of shaft, A, provided with a ratchet and disk, h,said disk inclosing the side of said ratchet, the periphery of said diskand the apices of the ratchet-teeth lying in the same circumference,bearing-block I), provided with outwardly-projecting horizontal portion0, said portionprovided with bearing-lugs c, pawl (1, provided with theangular portion engaging with said ratchet,journals d, formed on eitherside of the ratchet and having bearing in lugs c, and lower weightp0rtion,e, and cap F, composed of journal-cap portion f, fitting overthe shaft-journal, and outer portion, f, that incloses the ratchetwheeland pawl, said outer portion provided with the circular depressions f inwhich the upper portions of journals d respectively lit, In testimonythat I claim the foregoing to 10 said pawl engaging on one side with theinner be my invention I have hereunto set my hand wall of the outer capport-ion and on the opthis 12th day of July, A.
